Abstract
? 2022 Elsevier B.V.The aim of these comments is to bring attention of the scientific community to significant errors reported in the commented paper. The authors of the commented paper claimed the preparation of solid solutions Bi1?xHoxFeO3 with x = 0, 0.2, 0.4, 0.6, and 0.8. The obtained samples have been intensively characterized by different methods. However, the reported X-ray diffraction data unambiguously showed that single-phase solid solutions Bi1?xHoxFeO3 have not been obtained, and mixtures of other phases have been studied.
